CORN-PLANTER ATTACHMENT.

To cZZ vifi/1,0m 'it may concern Be it known that fl, Jeux B. Amazon, a citizen ot' the United States, residing at `Plover, in the county et' Pocahontas and State of iowa, have invented certain new and useful improvements in Corn-'Planter rrttaclnnents; and I do declare the follow- 'inO to be a Yt'ull, clear, and exact description oli the invention, such as will enable others skilled in the art to which it appertains to This invention relates to corn planters, and the object et the saine is to produce an attz'ichraei'u capable ot being applied to such a machine and including a gage rigidly held by the framework oit the planter and adjustable with respect` thereto so that the shoe ot the plaider may be caused to enter the earth only to the distance required.

This object is carried out by constructing the attachment in the manner hereinafter more 'tally described and claimed, and as shown in the drawings wherein- Figure l is a side elevation and Fig. :2 a plan View ot a corn planter with this attachinent in piace thereon, one ot the seed boxes in F 2 being broken away. Fig. 3 .'s a trout elevation oit' the planter and at- J.fuzlunent. Fig. l is an enlarged longituilinal section ot the shoe form oit gage and a portion of its support taken about On the line et---ilot' Fig. Q. Fig. is a perspective detail oit the two members constituting the remainder et said support, and Fig. (S is a perspective detail oit' the clip plate by which the support is attached to the shoe. Fig. 7 is a perspective detail ot a moditied form on a reduced scale, showing the wheel t'orm of gage and part of the support therefor. Fig. S is a side View and Fig. 9 a cross section on the .line 9@ of Fig. 8 showing an amplilied :torni of this device. Fig. 10 is a perspective detail of the lowermost member and the bearing :tor the wheel-shaft which is used with the t'orn oi machine shown in Figs. S and 9.

In the drawings the letter C designates a corn planter ot' any suitable type, but the one illustrated herein has a framework consist.- ing of front and rear bars F and R carrying seed boxes B, B, at their extremities, and shoes S beneath said boxes. The construe tion and mechanism ot this corn planter is not essential to the present invention, save that I propose to make my attachnient in such form that it may be applied Speeicaton of Letters Patent.

to the 'framework ol a corn planter ot' thisl character, or it the corn planter be of sonic dillerent type the support and connection ot' this attachment will be modified acoordingly.

Coming now more particularly to the details oit' the present invention, the numeral l designates a llat shoe made of sheet metal perhaps six inches wide and tapering and upturned at its front end as at 2, and v23 is a rib as of strap inelal which is secured along the length o't' said shoe on its upper side by rivets or bolts Lt whose heads are countersunk 'uno the lower it'ace oit the shoe and whtse nuts stand above said rib so that they will not become clogged with earth. This rib extends forward of and rises troni the shoe as best seen in Fig. l, and its upper extremity 5 is vertical and is pierced with a series ot holes (3 as best seen in Fig. 3; and through one of said holes is passed a bolt 7 which may be connected with the lront bar l" oit the planter' Lli'rainc in any suitable way, preferably by means ol a clip S ot U-shaped construction which the tightening up et' the nut on the bolt i' clamps upon said front bar in a manner which will he clear. The up turned end of the rib 3 and this attaching device therefore constitutie a means 'tor supporting the front end ot' the shoe.

Secured upon the rear end of the rib is a clip plate bestseen in Fig. This consists et' a short strip l() of metal having its center 1l unbent and pierced with a hole l2, and its ends are connected by rivets or bolts 18 with the rib qtheir heads preferably being disposed downward and countersunk in the lower tace of said rib and their nuts disposed above the downturned ends ot' the clip plate so that they may be readily accessible. rlhrough said hole 1Q projects a bolt llt whose head l5 stands beneath the upbent center l1 ot the clip plate and whose shank rises therefrom as seen in Fig. 4l, and two nuts 16 and 17 are engaged with the tlneaded shank of this bolt. This element terms one portion o'tl the support at the rear ot the shoe. The other portion, thereof is made up of the two members telescopically mounted on each other, and their construetion is b-cst seen in Fig. 5. The lowerniost ineinber 20 has its lower end bent to the rear as at Q1 and pierced with an eye through which said bolt projects, and the nuts 16 and 17 are tightened upon said lower end above and below it as seen in Fig. 1.` The body of this member 2O is pierced with a bolt hole 28, and its upper end formed into two tongues 2-1 which are bent forwardly in parallelism with each other. The other member 30, also of strap metal, is of a size to pass between said tongues 2-1, and its lower end is pierced with a series of holes 31 which may be brought successively into register with said hole 23 so that they may be connected by a bolt 32-thereby permitting the adjustment of these members upon each other in addition to the adjustment between the lower end 21 of the lower member and the bolt 111 which is permitted by means of the two nuts 16 and 17'. The upper end of the upper member 30 is connected to the rear bar R of the planter frame in any suitable manner, preferably by being turned over as shown at 38 and its body and its turned over portion pierced with alined holes 34 through which may pass a bolt 35 beneath the frame bar 1t as seen in Fig. 1. lVhen this bolt is tightened up the hooked upper end of' the upper member 30 is clamped upon the ban-when it is loosened this end may be adjusted longitudinally of said frame bar R, or when the bolt is Withdrawn this member can be entirely disconnect-ed therefrom.

All parts of the device are preferably of metal, and those that are subjected to the most wear may be tempered. As above suggested, with other types of corn planters it may be necessary to alter the structure slightly, but l prefer to retain the fiat, rather wide shoe 1 and the rib 3 secured alongits upper face and upturn-ed at its front end, and 1 prefer to connect the extended front end of this rib with the framework of the corn planter at one point, while 1 prefer to connect the rear end of this rib by some extensible form of connection with the framework of the corn planter at another point.

From this construction it follows that when this device is attached to a corn planter, a slight adjustment of the position of the shoes may be effected by loosening the nuts 16 and 17 and resetting them so as to let the planter shoes farther downward or draw them farther upward with respect to the lower end of the drill; and a greater degree of adjustment may be effected, or the same slight degree of adjustment effected through a different path, by setting the bolt 32 in some of the other holes 81 through the upper member 30, and then adjusting the nuts on the bolt 111 as above described. 1n Fig. 2 1 have shown the attachment as applied to the corn planter frame outside its shoes, although it is not necessary that it occupy that exact position.

In Fig. 7 I have shown a slightly modied form of this attachment, wherein the gage is in the form of a pair of rollers 1 (instead of the flat shoe 1) each having a hub 2 adjustable lengthwise by means of a set screw 3 on a longitudinal shaft 11, and the latter is journaled in bearings 5 formed at the extremities of lateral offsets 15 which are in effect the heads of upright bolts 111 whose threaded shanks carry the nuts 16 and 17 above described and are thereby adjustably held in the eyes of the rearwardly bent ends 21 of said lowermost members 20 described above. W ith some kinds of soil it may be desirable to substitute rollers 1 for the flat shoes 1 above described, and it is obvious that by removing the nut 16 on the bolt 141 the latter may be entirely withdrawn and the bolt 14 substituted therefor, whereby the shaft 4 and its rollers will be adjusts ably supported in the same manner as the shoe form of gage. This modification of my invention, however, possesses the additional advantage that if collars G are placed on the shaft t and rendered adjustable by set screws 7', the entire shaft can be held in one position between the bearings 5 or can be adjusted longitudinally therein; whereas by loosening the set screws 3 the hubs 2 of the wheels 1 may be adjusted with re spect to the shaft. This renders it possible to locate the wheel or roller form of gage either outside of the planter shoes S as shown in F ig..2 with respect to the shoe form of gage, or inside said shoes if desired7 and at such a distance from them as the nature of the soil demands.

1t is quite possible that in some cases the user may prefer to employ the roller form of at one side of the corn planter and the shoe 'form of gage at the other side, or at one or both sides of the machine he may employ both forms of gage, putting the shoe form for instance on the outer side of he planter shoe, as seen in Figs. 8 and 9, and the roller form of gage on the inner sioe of said shoe and spacing each form as far from the shoe S as the nature of the soil demands. 1n this case the wheels or rollersI 1 have their hubs 2 adjustable lengthwise by split pins or other devices 3 on the shaft 4 and the latter is journaled in bearings 5 formed at the extremities of plat-es 15. As seen in Fig. 10, each plate is pierced with an eye threaded onto the kupright bolt 14C beneath the rearwardly bent portion 21 of the lowermost member 20 and above the lower nut 17 g and therefore this shaft and the wheels which it carries is adjustable vertically when said lowermost member is adjusted. 1n this case, the setting of the nuts 16 and 17 pushes the shank of the bolt 14 downward, depresses the and therefore lets the planter shoe into the earth a lesser distance, whereas a reverse setting of the nuts raises the gage and lets the planter shoe S enter the ground to a greater degree.
